Question

04. The entropy change can be calculated by using the expression AS - ( /).When water freezes in a glass beaker, choose the correct statement amongst the following:O AS (system) decreases but AS (surroundings) remains the same.(1) AS (system) increases but AS (surroundings) decreases.(1) AS (system) decreases but AS (surroundings) increases.(iv) AS (system) decreases and AS (surroundings) also decreases​

Answer 1

The entropy change can be calculated by using the expression ΔS = qrev/T . When water freezes in a glass beaker, choose the correct statement amongst the following :  

(i) ΔS (system) decreases but ΔS (surroundings) remains the same.  

(ii) ΔS (system) increases but ΔS (surroundings) decreases.  

(iii) ΔS (system) decreases but ΔS (surroundings) increases.  

(iv) ΔS (system) decreases and ΔS (surroundings) also decreases.
